Application filed August 3, 1922, Serial No. 579,369.

This invention relates to ships davit contrivances for facilitating the lowering an raising of a ships anchor without fouling the sides or injuring the deck of the vessel. To carry out the invention the ship is pro- 'vided with a carrier which supports the anchor in its raised position. Said carrier is rovided with a swingable portion to which the anchor is attached, and the construction is such that when the carrier is in its outermost position said swingable portion swings ciear of the vessel and hence permits the anchor to engaging any partof the ship. The carrier remains in its outermost position while the anchor is in lowered position, so that when the anchor is raised it rests first upon the swingable portion clear of the vessel, and said swingable portion is then rotated to its initial position upon the carrier and the latter drawn inwardly. I v A It is a further object of this invention to provide means whereby the anchor upon being raised will adjust itself in position upon the swingable member.

Another object of this invention is to provide means whereby the anchor willbe automatically locked in position upon the carrier, thus preventing slipping or rocking of the anchor due to the motion of the vessel.

7 Other features and advantages will hereinafter appear.

In the accompanying drawings:

showing my invention applied to a vessel, the anchor being in raised position and resting upon the carrier V --y Figure 2 is a view similar to Figure 1, but with the anchor in position for lowering;

Figures 7 and 8 are enlarged details showing how the upper end of the movable mem-' ber operates to position the anchor properly with respect to the support; 7 Figures 9 and 10 are views of the lower end of the movable member showing additional means for properly positioning and supporting the anchor thereon.

Referring to the drawings,

a portion of a vessel having a side 10 and a there is shown deck 11, the davit contrivance being shown I applied to the deck. with an anchor which may be of any ordinary type and has preferably a shank 12, a stock 18, a ring 14 at one end of the shank,

and arms 15 at the other end of the shank,

said arms being in a plane perpendicular to the plane of the shank and stock. For raisprovided the usual cable "17 tied to the ring 14 at one end, and

the other end of the cable being wound'by any suitable mechanism, such a winch. The anchor is lowered; of course, by releas ing the cable so that the anchor can fall under its own weight.

It is desirable that V of the vesseh For this purpose there must be provided'means whereby the anchor may be carried from the deck of the vessel to a point beyond'the side thereof before'the anchor is allowed the anchor may be fully raised and returned to the deck without engaging the vessel. To perform these functions there is provided a carrier 20 mounted for outward and inward movement, toward and away fron'r-the side of the vessel, preferably upon guide rodslZl holding the anchora considerable distance away from the side there is provided an anchor support 30 fixed to a bracket 28 which is pivotally mounted at 29 on the end to fall, and means whereby The vessel is provided when the anchor is raised or lowered it shall not foul the side of an outwardly projecting arm 31 fixed upon the carrier. Said support is provided with a bent-off portion or arm 33, which, when the support 30 has swung about the pivot 29, forms an outward extension considerably beyond the vessel, the anchor being suspended from the end of said arm 33 in position for lowering (see Fig. 2). The anchor may thus be lowered without danger of its contacting with the vessel and avoid ing any possibility of injury to the ship... The outer end of arm 33 may be provided with a pulley 34; over which the cable 17 operates. p

lVhen the anchor is to be raised, rope 17 is wound up, thus tending to draw carrier 20 inwardly since the rope 17 passes beneath a pulley 36 fixed to the carrier, the latter, however, being held in its outward position because rope 25 is wound up. Until the anchor is fully drawn up to pulley 34, support 30 is held in the Figure 2 position substantially vertical, the weight of the anchor tending to rotate the support about pivot 29 to keep said support in con tact with the side of the vessel. lVhen the anchor reaches the pulley 34, however, further pulling upon rope 17 will draw carrier 20, support 30 and the anchor inwardly along guide rods 21 until the carrier reaches its innermost position where it may be held by fastening rope 17 against unwinding. To lower the anchor, rope 25 is wound to draw the carrier outwardly, rope l'ibeing released sufliciently to permit said outward movement. Vllhen the carrier has reached its outermost position, further release of rope 17 will permit the anchor by its weight to rotate member 30 about pivot 29 to the Figure 3 position. Still further release of rope 17 will permit the anchor to hang freely from the end of arm 33 some dis tance removed from the side of the vessel,=

from which position the anchor may be freely lowered by further unwinding of rope 17, It will thus be apparent that the support 30 maintains the anchor out of contact with the ship at all times, releasing the anchor beyond the side of the vessel when it is to be dropped, and taking it up again beyond the vessel when itis raised.

To enable the anchor while being raised to position itself properly upon, the sup port 30, there may be side of the pulley 34 a tends the pulley 34:, and hence the anchor, which are in a plane perpendicular to the plane of the ring, will be located substantially perpendicular to the plane of the ring. Positioned at the lower end of support 30in a plane perpendicular to the plane of pulley 34, and hence parallel to the plane ofarms 15,1's across-bar 12 having arm-supports 43. As the anchor-ring cam surface 10 which provided adjacent one to turn the ring 14 into the plane of arms 15 of thereaches its Figure 8 position the arms 15 will be turned into a plane parallel to cross-bar 42, and further pulling upon rope 17 will tilt support 30 inwardly to the Figure 3 position, and arms 15 will come to rest upon cross-bar 42 and arm-supports 3. The action is thus self adjusti'i'ilg. The arms 43 are adjustably mounted on the cross-bar 42 to accommodate anchor arms of various'sizes, and the cross-bar' t2 is adjustably mounted upon the member 30 to accommodate anchors having various sized shanks.

When the support 30 and the anchor are tilted inwardly against the carrier, and the latter has been pulled inwardly, the lower end of the support and anchor may restupon a shelf 45 fixed to the carrier-supporting mechanism, and outer braclret 22. To prevent rocking or slipping of the anchor upon the shelf due to movement of the boat, there may be pro vided upon the shelf hooks 47 which engage over the arms of the anchor.
